F&P GW609 pump oscillates but won’t spin

[richyg1975]

I have a F&P GW609 washing machine. When it gets to the drain phases of the washing cycle the pump fails to spin and hums and gets warm before the washing machine switches off. The pump spins easily by hand so is not jammed and I bought a new pump thinking the pump was faulty but the same problem is present with the new pump. The pump seems to be receiving power ok and sort of in time with the main motor for the washer but just fails to turn?

Pump is fed directly from the motor controller, so presumably it isn’t delivering 230vAC.

If you go into diagnostics (see Sticky at top of forum), you can manually turn the pump on and off by using the Regular button, rather than as part of a wash programme.

thanks Penguin, I tried that with the same result, the pump turns very slowly, eg would probably take 10-20 seconds to do one revolution if power remained on long enough. The other thing I have found is that after trying the pump, when the washing machine eventually cuts out I have disconnected the pump, the coil is quite hot, I measure the resistance and it’s quite high (about 50ohms) and gradually drops back to around 33 as the coil cools which is what I believe the resistance is supposed to be. I have tried this with both my old pump and the new one. I am wondering if maybe my circuit board is fried and the pump is not getting the correct type of power? I can’t think where else the problem could be?

Yup, motor controller is the circuit board. If you have a test meter you could check the output – use extreme caution, live testing is always hazardous.

It could be as simple as a bad solder joint on the board – trace the circuit back from where the connector joins on. If a component has actually failed, you are looking at replacing the board.
